  Although the underwater suspended matter collection device described in Patent Document 1 can efficiently collect underwater suspended matters, it requires electric power to generate bubbles and sucks water containing suspended solids. Therefore, there is a problem that the amount of power consumption for absorbing water is large. In addition, in order to collect a wide range of suspended substances floating on the water surface or in the vicinity of the water surface, it is necessary to move the underwater suspended matter collection device, which raises the problem of increased work costs.

  The water purification device described in Patent Document 2 is similar to the problem described with respect to Patent Document 1, and generates a spiral water flow and absorbs water in order to constantly suck water containing suspended solids by a suction pump. Therefore, in order to collect a wide range of suspended substances floating on or near the water surface, it is necessary to move the water purification device, resulting in a problem that the operation cost becomes high.

  Furthermore, since suspended substances floating on the surface of the water flow under the influence of the wind, it is desirable that the sampling device is not fixed at a fixed location but can be easily changed. Alternatively, it is desirable for the sampling device to follow the suspended matter that has flowed under the influence of the wind. As shown in Patent Documents 1 and 2, when the suspended substance collection device is fixed in a certain place, it is difficult to recover the suspended substance when it is moved by the influence of the wind, and the recovery rate decreases. Become.

  The present invention has been made in view of the above problems, and the purpose thereof is low power consumption for absorbing water containing suspended solids, and without forcibly moving the sampling device within the water area. It is an object of the present invention to provide a suspended substance collection device capable of efficiently collecting a suspended substance in a wide area by suction.

  In order to achieve the above object, a suspended matter collecting apparatus according to claim 1 has a water tank that is open at the top and stores water containing suspended substances therein, and a water absorption pump that absorbs the water stored in the water tank. A plurality of water feeding means for feeding the absorbed water to the outside of the water tank, and a plurality of water tanks provided across the inside / outside of the water tank and having a water tank lower end and a water tank outer lower end set at a position higher than the water tank lower end. The plurality of pipes take water containing suspended solids into the water tank using the principle of siphon.

  Therefore, since the suspended matter collection device of the present invention takes in water containing suspended solids using the siphon principle by using a plurality of pipes, the power for taking water containing suspended matter is taken. It is not necessary, and it is possible to realize a suspended substance collection device that consumes very little power to absorb water.

  According to a second aspect of the present invention, the pipe member is attached to the water tank, a floating body is fixed in the vicinity of the lower end outside the water tank, and an upper portion of the floating body is a telescopic tube biased in an extension direction. Regardless of the amount of water in the water tank, the lower end outside the water tank is maintained at a substantially constant position in the vicinity of the lower surface of the water. Water with a high concentration of substances can be taken in stably.

  As described in claim 3, an upper slit pipe that opens upward is attached to each of the water tank outer ends of the plurality of pipe materials in a direction perpendicular to the pipe material and radially with respect to the water tank. Therefore, it is possible to take water containing suspended substances efficiently in a wide range.

  As described in claim 4, the upper opening of the water tank is circular, and the pipe material is movably mounted on the opening edge of the water tank, and the pipe material is attached to the opening edge of the pipe material. A sail for rotating and moving along with the wind is provided along the way, so the suspended matter collection device can take water containing suspended matter while rotating and moving freely in the water area. Cost can be greatly reduced.

  As described in claim 5, the attachment of the upper slit pipe to the pipe material is performed in a predetermined manner with the upper slit pipe in a horizontal plane including the upper slit pipe and the lower end outside the water tank of the pipe material being substantially centered. Therefore, when the suspended matter collection device rotates and receives wind in the water area, a spiral flow is formed on the surface of the water and the suspended suspension is suspended. Suspended substances will be attracted, and suspended substances can be collected more efficiently.

  According to the suspended matter collecting apparatus of the present invention, water containing suspended solids is taken from a plurality of pipes according to the principle of siphon, so that electric power for taking water containing suspended matter is not required. Therefore, it is possible to realize a suspended substance collection device that consumes very little power to absorb water. Furthermore, according to another configuration of the present invention, it is possible to stably and efficiently collect a suspended substance floating on or near the water surface in a wide range.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of the suspended substance collection apparatus of the present invention, and FIG. 2 is a schematic cross-sectional view taken along the line AA of FIG. In the present embodiment, aquatic is assumed as a suspended substance.

  The suspended matter collecting apparatus 10 uses a bucket-type water tank 12 whose upper part is opened in a circular shape, water supply means for absorbing water stored in the water tank 12 and feeding it to the outside of the water tank 12, and the principle of siphon, The inside of the water tank 12 has eight pipe members (siphon tubes) 22 for taking water containing suspended substances. The water supply means includes a water absorption pump 36, a water absorption pipe 38, a water discharge pipe 40, and a flexible pipe 50.

  The water absorption pump 36 has a water absorption pump base 34 attached to a water absorption pump base 35 provided in the center of the water tank 12, and is installed on the water absorption pump base 34. The water absorption pipe 38 of the water absorption pump 36 extends to the vicinity of the bottom of the water tank 12, and the water discharge pipe 40 penetrates the bottom of the water tank 12 and is connected to a flexible pipe (water guide pipe) 50 through a joint joint 48. Yes. The flexible pipe 50 extends to, for example, a sedimentation tank installed on the shore, and water containing suspended solids taken into the water tank 12 passes through the water suction pipe 38, the water discharge pipe 40, and the flexible pipe 50 by the water suction pump 36. And sent to the settling tank.

  The tube material 22 is formed in a bowl shape, and the upper slit tube 14 opened upward is attached to the water tank outer lower end 22a via the universal joint 16 at a right angle to the tube material 22 and radially with respect to the water tank 12. Yes. The water tank inner lower end (siphon discharge port) 22 b is configured to be located near the bottom of the water tank 12. A floating body 18 is fixed to the pipe material 22 at the upper portion of the universal joint 16, that is, the connection portion between the upper slit tube 14 and the pipe material 22, and the upper portion of the floating body 18 is a telescopic tube 20 biased in the extending direction. . All the pipe materials 22 are fixed to the siphon pipe connecting material 56.

  Due to the floating body 18 fixed to the pipe material 22, the telescopic pipe 20 provided in the pipe material 22, and the water tank 12, an edge (siphon intake) 15 a of the upper opening of the upper slit pipe 14 is formed in the water tank 12. Regardless of the amount of water, it is configured to be approximately 2-3 cm below the water surface at all times. That is, when a large amount of water is taken into the water tank 12 and the entire water tank 12 sinks, the telescopic tube 22 shrinks by the amount of the sink, and as a result, the position of the groove 15a of the upper opening of the upper slit tube 14 does not change. It is configured. That is, the telescopic tube 20 can absorb the ups and downs of the water tank 12. By this action, it is possible to continuously take in water having a high concentration of suspended substances from the upper slit tube 14 at all times.

  For example, the upper slit tube 14 may be formed by making a vertical cut in a vinyl chloride pipe so that the cut faces upward. The outer end 15b of the upper slit tube 14 is closed. This is because water can be taken from the groove 15a of the upper opening more effectively. Furthermore, the length of the upper slit tube 14 can be optimally determined in consideration of the size of the water tank 12, the capacity of the water absorption pump 36, and the like.

  Further, one end of an air vent pipe 24 to which the check valve 30 is attached is connected to the pipe material 22 in communication with the inside of the pipe material 22, and the other end of the air vent pipe 24 is connected to an air vent pipe coupling portion 26. Yes. There are a total of eight air vent pipes 24, and one end of each is connected to the air vent pipe coupling portion 26. The air vent pipe coupling portion 26 is connected to a vacuum pump 28.

  The check valve 30 has a function of allowing air to pass only in one direction. In the present embodiment, the check valve 30 is configured to allow the air flow from the pipe member 22 to the air vent pipe coupling portion 26 and not to the reverse. ing. By operating the vacuum pump 28, the inside of the tube material 22 is evacuated through the air vent tube coupling portion 26 and the air vent tube 24, and the tube material 22 is filled with water containing suspended solids. Water intake by will be started. Further, by opening the check valve 30 in the time zone where no water is generated, such as at night, air enters the pipe material 22, and water intake by the pipe material 22 is stopped by stopping the siphon principle. A mooring jig 60 is provided on the upper part of the vacuum pump 28, and it is possible to limit the movement of the suspended solid collection device 10 to a certain range through a wire or the like through the mooring jig 60.

  A ball roller 54 is installed at the lower end of the siphon tube connecting member 56. An annular buffer member 55 is placed on the upper end of the water tank 12 in contact with the ball roller 54 so that the tube material 22 can smoothly rotate and move. As the buffer member 55, for example, a rubber plate or the like may be used.

  The air vent pipe coupling portion 26 and the vacuum pump 28 are mounted on a vacuum pump rotary base 32 installed on a vacuum pump base 37, and the sail 58 is attached to a part of the pipe material 22. Thereby, the group of the water tank 12, the water absorption pump base 35, the water absorption pump base 34, the water absorption pump 36, the water absorption pipe 38, the water discharge pipe 40, the vacuum pump base 37, the upper slit pipe 14, the floating body 18, the telescopic pipe 20, and the pipe material 22 are obtained. The group of the air vent pipe 24, the vacuum pump turntable 32, the vacuum pump 28, and the sail 58 can be moved separately. That is, when the sail 58 receives wind in the water area, the upper slit tube 14, the pipe material 22, and the like move while rotating around the water tank 12 left or right.

  In addition, the universal joint 16 is used for the connection between the upper slit tube 14 and the pipe material 22, and the upper slit tube 14 can swing around the universal joint 16 to the left or right within a specific angle range. It can be configured. As a result, when the sail 58 receives wind and the upper slit tube 14 rotates and moves, the upper slit tube 14 swings to the left or right to form a spiral flow.

  Further, the water absorption pump 36 is controlled to be turned on / off by a water absorption pump upper water level sensor 42 and a water absorption pump lower water level sensor 44 in order to manage the amount of water in the water tank 12, and water that is always taken in by the pipe 22. The water level is configured to be between the upper water level sensor 42 and the lower water level sensor 44. That is, when the water level taken by the pipe 22 reaches the upper water level sensor 42, the water suction pump 36 is operated to continue sending the taken water from the water tank 12, and the water level drops to the lower water level sensor 44. The operation of the water absorption pump 36 is stopped when The above-described control is performed via a control line 46 extended between the water absorption pump upper water level sensor 42 and the water absorption pump lower water level sensor 44 and the water absorption pump 36.

  The sail 58 is attached to a part of the pipe material 22 as described above, and a material such as a plastic resin material, a cloth material, and a plate material can be used as appropriate. In order to efficiently receive wind, the sail 58 may be freely set at an attachment angle when it is attached to the pipe material 22. Here, the sail 58 may be attached to the air vent pipe 24 or the annular siphon pipe connecting material 56 instead of the pipe material 22. In FIG. 1, in order to show that the sails 58 can freely set the angle, the eight sails 58 are shown with arbitrary attachment angles.

  FIG. 3 is an operation explanatory diagram in the water area of the suspended matter collecting apparatus 10 according to the present invention. Hereinafter, the operation of each part of the suspended solid collection device 10 of the present invention will be described in detail while explaining the operation of collecting the suspended solid floating on or near the water surface. However, in FIG. 3, the range in which the suspended solid collection work should be performed is specified, and the wire 68 is stretched from both sides of the water area so that the suspended solid collection device 10 moves within the range. . That is, the rotational movement range of the suspended substance fraud apparatus 10 is limited to a range along the wire 68. The wire 68 is fixed by anchoring anchors 70 driven on both banks through the anchoring jig 60 of the suspended substance collecting apparatus 10, and the anchoring jig 60 is configured to be rotatable.

  After the suspended matter collecting device 10 is disposed at a predetermined position, the vacuum pump 28 is operated. Then, the air in each tube material 22 is extracted through the air vent tube coupling portion 26 and the air vent tube 24 to be in a vacuum state, and each tube material 22 starts to be filled with water containing suspended substances.

  When the water filled in the tube 22 reaches the part straddling the water tank 12, when the operation of the vacuum pump 28 is stopped, the water containing the suspended substance is taken into the water tank 12 by the siphon principle. start. Water intake is continued as long as no air enters the pipe 22.

  Water containing suspended solids continues to be taken into the aquarium 12, but when the water level reaches the upper water level sensor 42 of the water pump, the water suction pump 36 is automatically activated, and the water containing suspended solids is absorbed by the water absorption pipe 38. The water is fed to the settling tank 62 installed on the shore in the water area through the water discharge pipe 40, the joint joint 48, and the flexible pipe 50. When the water level reaches the water absorption pump lower water level sensor 44, the water absorption pump 36 is automatically stopped. Therefore, in the suspended solid collection device 10 of the present invention, no electric power is required to take water containing suspended solids, and the water absorption pump 36 that absorbs water in the water tank 12 is operated intermittently. Therefore, the power consumption for water absorption can be kept low. In addition, the capacity of the water absorption pump has so far required a high-lift pump that emphasizes the suction power in order to collect more suspended solids from a wide range. Since the pump model can be selected according to the head to the settling tank and the capacity of the processing tank, the cost of the pump equipment is also low.

  The flexible pipe 50 is made of a flexible material, and has a sufficient length so that the suspended solid collection device 10 can move over a wide range. Although not shown, the sedimentation tank 62 is a treatment tank 66 installed on the shore through a second water storage tank (not shown) from which dust such as twigs is removed in the first water storage tank. To be processed by a pump. For this purpose, the sedimentation tank 62 and the treatment tank 66 are connected by a water conduit 64.

  As described above, the upper slit tube 14 is connected to the pipe member 22, and the edge 15 a of the upper opening is configured to be positioned approximately 2 to 3 cm below the water surface regardless of the amount of water in the water tank 12. ing. The eight upper slit tubes 14 are arranged radially around the water tank 12. Accordingly, water having a high concentration of suspended solids approximately 2 to 3 cm below the surface of the water is efficiently and stably taken over a wide area from the edge 15a of the upper opening of the eight upper slit tubes 14. Become.

  On the other hand, suspended substances floating on the water surface or in the vicinity of the water surface are easily moved by the wind in the water area, so it was necessary to forcibly move the suspended substance collection device following the moved suspended substances. However, since the suspended solid collection device 10 of the present invention is provided with the ball roller 54 and the sail 58, it can move in the water area while being rotated by wind. However, in the example shown in FIG. 3, it rotates and moves within a range along the wire 68.

  In other words, the turbid substance collection device 10 of the present invention sucks the suspended substance naturally along the wire 68 when the suspended substance has moved to the range where the suspended substance collection work should be performed by the wind of the water surface. It is possible to collect. Therefore, since the suspended matter collecting apparatus 10 freely rotates within the range where the suspended matter collecting work should be performed, there is no need to forcibly or manually pull, and the working cost can be greatly reduced. It becomes.

  The upper slit tube 14 swings to the left or right when the suspended substance collection device 10 receives the wind in the water area and rotates to form a spiral flow on the water surface. The suspended substances can be collected more efficiently.

  The significance of swinging the upper slit tube 14 to the left or right is that even if the suspended substance cannot be aspirated and collected by one upper slit tube 14, another adjacent upper slit tube 14 approaches the suspended substance and aspirated and collected. There is a point that can be done. Therefore, it is possible to suck and collect suspended substances in the water area more efficiently.

  In addition, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the meaning of invention. For example, the number of upper slit tubes 14 may be changed. Further, the shape and material of the sail 58 may be changed. Furthermore, the dimensions of each member are not limited to the embodiment, and the design can be changed as appropriate according to the water area from which the suspended substance is to be removed.

  INDUSTRIAL APPLICABILITY The present invention can be used in closed water areas or microfluidic water areas where suspended substances containing phytoplankton, etc. are retained in dam lakes, ponds, lakes, reservoirs, dam coves, moats or sea areas. . If various design changes are made without departing from the gist of the present invention, for example, oil recovery at the time of oil spill or the like can be diverted to recovering what is floating on the water surface.
